Aluminium Tank Anodes

Product description:

Description:

Aluminum Tank Anodes are used to complement the coating at areas of exposed steel prolonging the life of the coating and structure. Hydrogen is evolved from aluminium anodes and thermite sparking may occur when light alloys impact on rusty steel. Therefore there is a height restriction in cargo/ballast tanks in tankers that anodes are not located at a height (in m) greater than 27/W where W is the total mass (in kg) of the anode and insert.

Aluminum alloy anodes can be used for the protection of storage tanks and are frequently installed on ship hulls and jetties. They also have a particular use in the protection of sub sea pipelines, oilrigs and semi-submersibles.

The electrochemical performance of aluminum makes it an attractive galvanic anode material, especially in low resistivity applications such as seawater. Compared to magnesium, aluminum's lower driving potential and high current capacity per pound make it an excellent choice for long life saline cathodic protection systems.
